Although the SIP History-Info header is the solution adopted in IETF,
the non-standard Diversion header is nevertheless widely implemented
and used for conveying call-diversion-related information in SIP
signaling.
This document describes a recommended interworking guideline between
the Diversion header and the History-Info header to handle call
diversion information. In addition, an interworking policy is
proposed to manage the headers' coexistence. The History-Info header
is described in RFC 4244 and the non-standard Diversion header is
described, as Historic, in RFC 5806.
Since the Diversion header is used in many existing network
implementations for the transport of call diversion information, its
interworking with the SIP History-Info standardized solution is
needed. This work is intended to enable the migration from non-
standard implementations and deployment toward IETF specification-
based implementations and deployment. This document is not an Internet
Standards Track specification; it is published for informational purposes.
